Kodi ntchito ya kapangidwe ka chakudya cha ether ya cellulose ndi iti?

Fotokozani:

Zakudya zopangidwa ndiethers a cellulose

Munda waukadaulo:

Kapangidwe kameneka kakukhudzana ndi zakudya zomwe zili ndi ma ether a cellulose.

Njira yakumbuyo:

Kwa nthawi yayitali zakhala zikudziwika kuti zimaphatikiza ma ether a cellulose mu zakudya, makamaka zakudya zokonzedwa, kuti ziwongolere zinthu zosiyanasiyana monga kukhazikika kwa kuzizira ndi/kapena kapangidwe kake, kapena kuti zikhale zolimba panthawi yopanga, zokonzedwa ndi makina kapena zokazinga. Kugwiritsa ntchito patent yaku Britain GB 2 444 020 kukuwonetsa zakudya zotere zomwe zimakhala ndi ether ya cellulose yosakhala ionic monga methylcellulose, hydroxypropyl cellulose, kapena hydroxypropyl methylcellulose. Methylcellulose ndi hydroxypropyl methylcellulose zili ndi "makhalidwe osinthika a thermos gelling". Zafotokozedwa momveka bwino kuti pamene yankho lamadzi la methylcellulose kapena hydroxypropyl methylcellulose litenthedwa, gulu la hydrophobic methoxy lomwe lili mu molekyulu limataya madzi, ndipo limakhala gel yamadzi. Kumbali ina, gel yomwe imachokera ikazizira, magulu a hydrophobic methoxy amabwezeretsedwanso, pomwe gel imabwerera ku yankho loyambirira lamadzi.

European Patent EP I 171 471 ikuwonetsa methylcellulose yomwe ndi yothandiza kwambiri popanga zakudya zolimba monga ndiwo zamasamba zolimba, nyama, ndi soya chifukwa cha mphamvu zake za gel. Methylcellulose imapereka kulimba komanso kugwirizana bwino ndi kapangidwe ka chakudya cholimba, motero imapereka kuluma kwabwino kwa ogula omwe akudya kapangidwe ka chakudya chokonzedwa. Ikasungunuka m'madzi ozizira (monga, 5°C kapena kutsika) isanayambe kapena itatha kusakaniza ndi zosakaniza zina za kapangidwe ka chakudya, soya ya methylcellulose imafika pamlingo wake wonse wopereka kapangidwe ka chakudya cholimba ndi mphamvu yabwino komanso yogwirizana.

Komabe, nthawi zina, kugwiritsa ntchito madzi ozizira kumakhala kovuta kwa wopanga chakudya. Chifukwa chake, zingakhale bwino kupereka ma ether a cellulose omwe amapereka zakudya zolimba zolimba komanso zogwirizana bwino ngakhale ma ether a cellulose atasungunuka m'madzi okhala ndi kutentha kwa chipinda.

Hydroxyalkyl methylcellulose monga hydroxypropyl methylcellulose (yomwe imadziwikanso kuti ndi yothandiza popanga zakudya) imadziwika kuti ili ndi modulus yocheperako poyerekeza ndi methylcellulose. Hydroxyalkyl methylcellulose zomwe zimakhala ndi modulus yocheperako sizipanga ma gels amphamvu. Kuchuluka kwa ma gels ofooka kumafunika ngakhale (Haque, A; Richardson; Morris, ER, Gidley, MJ ndi Caswell, DC mu Carbohydrate Polymers22 (1993) tsamba 175; ndi Haque, A ndi Morris, ER1nCarbohydrate Polymers22 (1993) tsamba 161).

Pamene ma hydroxyalkyl methylcellulose monga hydroxypropyl methylcellulose (omwe ali ndi modulus yochepa yosungira) aphatikizidwa mu zakudya zolimba, kuuma kwawo ndi kugwirizana kwawo sikokwanira kugwiritsidwa ntchito zina.

Cholinga cha njira yatsopanoyi ndi kupereka hydroxyalkyl methylcellulose, makamaka hydroxypropyl methylcellulose, yomwe ndi yofanana ndi hydroxyalkyl methylcellulose yodziwika bwino, monga hydroxypropyl methylcellulose. Mosiyana ndi zimenezi, zakudya zolimba zimaperekedwa ndi kulimba bwino komanso/kapena kugwirizana bwino.

Cholinga chomwe chimakonda kwambiri pakupanga kumeneku ndikupereka hydroxyalkyl methylcellulose, makamaka hydroxypropyl methylcellulose, yomwe imapereka zakudya zolimba zokhala ndi kuuma kwabwino komanso/kapena mgwirizano ngakhale hydroxyalkyl methylcellulose itasungunuka m'madzi okhala ndi kutentha kwa chipinda.

Chodabwitsa n'chakuti, zapezeka kutihydroxyalkyl methylcellulosePoyerekeza ndi zakudya zolimba, zakudya zolimba zodziwika bwino zimakhala ndi kuuma kwakukulu komanso/kapena kugwirizana kwakukulu.

Komanso chodabwitsa n'chakuti, zapezeka kuti ma hydroxyalkyl methylcellulose ena, makamaka hydroxypropyl methylcellulose, safunika kusungunuka m'madzi ozizira kuti apange zakudya zolimba zokhala ndi kulimba bwino komanso/kapena kugwirizana bwino.
